Patent DE-4220080-A1 (DE)
Inventor: SASSE BERNHARD
IPC: F16D59/02
Filed: 1992-06-19
Abstract: The invention relates to a method for the gentle operation of a brake by means of a brake lifter with a motor (1), a centrifugal pump and a hydraulic cylinder in which a working piston (5) is guided and connected to the brake via a piston rod (6). With the motor switched on, the working piston (5) is moved counter to an external force from its lower end position into its upper end position by means of the operating fluid pumped under the piston and, in the process, lifts the brake; with the motor (1) switched off, the working piston (5) is moved into its lower end position under the action of the external force. In the process, the brake falls inwards. Counteracting the braking force of the brake lifter in the region of the end position of the working piston (5) is a force which is variable with respect to time and limited in terms of travel. This counterforce is produced either mechanically-hydraulically or pneumatically. The braking force builds up when the brake falls inwards even before the working piston (5) has executed a piston stroke. <IMAGE>

Title: Magnetisation system for ABS rotation or velocity detector for ferromagnetic elements - uses main and auxiliary magnetic fields extending normal to detector magnet pole-face and in detector working direction
Inventor: MUTH MATTHIAS
IPC: G01P1/00
Filed: 1992-06-26
Abstract: The magnetisation system allows the detector magnet (15) to be magnetised via a main magnetic field (H1) normal to its pole-face (16), with comparison of the detector signal with a preset reference value. When the difference is outside a given range the main magnetic field (H1) is re-applied, together with an auxiliary variable, magnetic field (H2) extending in the detector working direction. The two signals are again compared and the variable magnetic field is adjusted in dependence on the remaining difference. Pref. the main and auxiliary field coils (12, 13) are positioned so that no component of the earth's magnetic field extends in the working direction. USE - For rotation or velocity detector for vehicle anti-locking braking system (ABS).

Title: Device for testing an electronic device
Inventor: BEHRENS KLAUS-PETER
IPC: G01R31/3181
Filed: 1993-02-23
Abstract: A device for testing an electronic device, and in particular a test set for integrated circuits, which is designed specifically for the testing of memories or logic/memory combinations, has a plurality of pin channels. Each pin channel comprises a sequence controller (17a to 17c) which is connected to a decompression control unit (18a to 18c). This combination is extremely quick and allows the respective pin channels to be assigned to an address pin or a data pin of a memory or to a logic pin (27c) of a test piece (21). A central control unit (22) supplies the necessary control commands to command memories (17a', to 17c') of the sequence controllers (17a to 17c). All sequence controllers (17c) which are assigned to a logic pin (27c) carry out essentially the same program, while a pin adaptation is carried out via a vector memory (19c). In contrast, sequencers (27a, 27b) which are assigned to an address pin carry out different pin-specific commands. The circuit architecture can be adapted in a simple way to varying pin definitions and is based on the solution statement "one source per pin". The architecture can also be applied in circuit board test sets and other electronic test sets. <IMAGE>

Title: Pneumatic air bag safety device with bursting pressure vessel
Inventor: IRMSCHER ILJA DR SC TECHN
IPC: B60R21/268
Filed: 1993-03-08
Abstract: In conventional vehicle air bag systems, use is made of inflating devices in which the compressed gas for filling the gas cushion is generated or released by igniting propellant charges. This results in undesired toxic compounds. Non-triggered propellant charges likewise constitute a potential risk. The novel air bag protection device is intended to ensure that the compressed gas flows out of the pressure vessel without ignition of pyrotechnical propellant charge, and optimum outlay characteristics of the outlay operation are thus achieved. According to the invention, the compressed gas is stored in a pressure vessel (1) consisting of brittle material. The pressure vessel (1) is supported in its position on a compression spring (4). When a defined limit deceleration is exceeded, the pressure vessel (1) is moved out of the zero position by the mass moment of inertia which arises, said vessel making impact on a wedge-shaped component and thus being made to burst. The rapidly expanding compressed gas flows into the gas cushion (2). The safety device is used for the protection of motor-vehicle occupants, both for the driver side and for the passenger side. <IMAGE>

Title: Gearing with positive prevention of torque reversal from both directions of rotation in combination with minimum gearing inertia
Inventor: STRACH LOTHAR
IPC: H02K7/116
Filed: 1993-04-20
Abstract: Gearing is used to alter the speed and torque ratio of an input and an output. The gearing components are here in rotation about their geometrical axis or about the axis of the gearing. In pauses between operation and with the energy supply to the driving motor switched off, the reactive effect of raised loads or other dynamic reaction forces is prevented by inserting into the gearing a worm gear with a shallow worm pitch or, alternatively, inserting cone or disc brakes. The worm gear results in poor driving efficiency, while cone or disc brakes are frictional elements and are subject to wear, with dangerous consequences in the event of inadequate maintenance - due to external influences, the friction coefficient can change very rapidly for the worse. In the present invention, a gearing has been inserted into a transmission member which executes torsional vibrations without, however, rotating about its own axis. This torsional vibration is used to move a positively engaging part out of a stand-by position into the space in which this torsional vibration takes place, the intention being by this means to prevent reaction forces in pauses between operation from turning the gearing backwards.
